BRON'ZING INSTRUMENT.

Application filed November 2, 1925, Serial No. 66,354, and. in GermanyNovember 14, 1924.

joining said bronze vessel, and the separation between the bronze powderand the tincture is effected by means of a tincture-tight and pierceablediaphragm stretched over the orifice of the tincture vessel and theseparation of the bronze powder from the outflow nozzle is also effectedby a similar diaphragm, so that the .mixing of the powder and thetincture can be carried out by piercing and tearing up the diaphragmswith a needle or the like to be inserted through the nozzle.

Two forms of construction of the improved bronzing instrument are shownin the accompanying drawings by way of example.

In longitudinal section:

Fig. 1 shows the first and Fig. 2 the second form of construction whilstFig. 3 shows a special piercing needle in elevation and cross section.

The tubular reservoir (1 contains only the tincture b. At its rim 0 thetest tube is closed by a frangible diaphragm d the edge 7" of which isleak-proof and hermetically fixed on the cylindrical part of the tube.

This tightness is ensured by an agglutinant with which the edge on thelower surface of the diaphragm is painted.

A sleeve 9 is placed on the test tube which has above the lower end ofits flange 71, an abutment groove 2'. According to Figs. 1 and 3 thissleeve, which is designed to receive the bronze powder, has above thebronze powder a preferably deeper groove Z serving as abutment for afrangible diaphragm m covering the filling of bronze powder and abovethe groove Z an outflow nozzle n on which the root end 0 of a brush 0 istied. The instrument shown in Fig. 2 differs from the instrument shownin Fig. 1 by the separation of the nozzle body p from the sleeve gcontaining the bronze,

over the edge 9 of which a diaphragm m is stretched same as over theedge 0 of the tubular reservoir. This frangible diaphragm is stretchedby placing a flangeh of the nozzle body 79 over it, the groove z" ofwhich comes to rest on the edge 9 of the sleeve.

I/Vith these instruments a simple wire can be supplied which at theupper end is bent to form a ring-shaped handle said wire being designedto be inserted into the orifice of the nozzle 71 so that it pierces thediaphragms m and (Z. By moving the wire handle to and fro in alldirections the diaphragrns are completely torn so that the bronze powderIn drops into the tincture b and so that further the access to thenozzle is made free. By shaking the instrument the bronze powder and'the tincture are intimately mixed. It is merely necessary to turn theinstrument up side down and to move it like a brush handle to cause theliquid bronze to flow through the nozzle a into the brush 0, by means ofwhich it can be applied. In order to avoid loss of material when theout-flow nozzle is open, the special piercing needle shown in Fig. 3 isused, the legs 8, s of which are semicircular in cross-section and bentso that the flat sides of the two arms are in contact the wire beingbent at the upper end to form a handle t and tapered at the lower end.This needle is so thick that it shuts off the orifice of nozzle n like astopper after the diaphragms have been pierced. The needle projects fromthe thick part beyond the brush so that the fingers which grip thehandle t do not come in contact with the brush.

Owing to the arrangement described it is impossible. that, theinstrument being in the horizontal position or shaken, tincture mixeswith the bronze powder, or that bronze powder can drop out through theupper diaphragms m, m and through the nozzle n and brush 0. On the otherhand the diaphragms prevent the access of air so that oxidizing of thebronze or of the tincture is securely prevented and the instrument canbe stored for a long time.

When the diaphgrams are pierced and torn in order that the instrument beused no tincture can flow out. No liquid bronze can further .flow outwhen the instrument is shaken for mixing the pow-der and tincturestainthe hand which shakes the instrument, as the nozzle 11 is closed by theneedle stopper 8, a during the shaking. In order to use the instrumentit is not necessary to pull out, re-insert, pull out again, turn upsidedown and re-insert again a stopper. If all the bronze should not havebeen used it is only necessary, to preserve the bronze in the instrumentto insert the stopper needle into the nozzle. The fingers will, at thisoccasion, not be soiled by bronze as the handle t of the needle can notbe inserted down to the brush.

The vessel for the tincture has been shown as a c lindrical reservoirresemblin a test,

tioned vessel covering-the bronze powder,

the second mentioned vessel having an upper extensionforming a hollownozzle, a brush on the upper ,end of saidouttlow nozzle, whereby aneedle may be inserted through said nozzle and second mentioned vesselfor piercing said two diaphragms so that the bronze powder may drop intosaid tincture and the instrumentcan be used as a brush for bronzing.

2. A bronzing instrumentcomprising in combination a vessel designed tocontain a tincture, a frangible diaphragm closing the upper open end ofsaid vessel, asecond vessel, mounted, on, said tincturev holding vesseland designed to contain bronze powder, a diaphragm on said secondmentioned vessel covering the bronze powder said second mentioned vesselbeing provided with an inwardly directed deep grove in the outer surfaceand at the upper end thereof engaging said diaphragm for securelyholding said diaphragm in place, said second mentioned vessel having anupper extension forming a hollow outflow nozzle, a brush on the upperend of said outflow nozzle, and a needle designed to be inserted throughsaid brushoutflow nozzle and second mentioned vessel for piercing saidtwo diaphragms so thatthe bronze powder drops into said tincture and theinstrument can beused as a brush for bronzing.

3. A bronzing instrument comprising in combination a-vessel designed tocontain a tincture, a diaphragm closing the upper open end of saidvessel, a-second vessel mounted on said tincture holding vessel anddesigned to contain bronze powder, a diaphragm closing the open top endof said sec ond ment oned vessel, a hollow outflow nozzle mounted on theupper end of said second mentioned vessel, a brush on the upper end ofsaid outflow nozzle, and a needle designed to be inserted'througl'i saidbrush outflow nozzle and second mentioned vessel for piercing saidtwodiaphragms so that the bronze powder drops into said tincture and theinstrument can be used as a brush for bronzing.

In testimony whereof I afiix my signature.
